He built two of the biggest companies in the history of the world.

He invented the musical synthesizer, at least the first one,

important electronic switches.

He got a patent on an underwater signaling device.

But perhaps most importantly, on February 14, 1876,

he filed the first patent for the telephone.

Of course, I'm talking about Alicia Gray.
